Document Summary

Reflex: simple, rapid response, primarily involved in spinal cord (no need for central nervous system) Voluntary: complex, starts without external stimuli (heavy/multiple coordination with nervous system) Rhythmic: combo of the first two; such as walking/running-on and off switch without lots of higher order control from the brain **not always discrete/single movement at a time. Needs inputs from the environment and feedbacks from the muscles on my body to find the movement. Control of voluntary movement: using planning, initiation, & execution- from highest order of central nervous system to the muscle fibre. Human nervous system: central nervous system: cerebral cortex, basal ganglia, brain stem, spinal cord, peripheral nervous system. It controls voluntary movements with primary function of planning & executing motor activities. Use of the motor cortex: for initiation of the movement includes: It has the memory storage, recall, and higher cognitive functioning: allowing a person to perceive, understand, and integrate all the senses.
